June 2025 — This Month Through Your Adapted Lens

I tried to use the vintage ones but most of those that I have are either too long or not long enough (50-58), or too soft at infinity (or both). I am thinking to try 135mm on the streets but they are a bit bulky, have not done that yet. And there is a fear of me missing an opportunity or just being generally too slow with the process (if with family).
Oh, a second thought looking back at this - have you tried some of the smaller 135s? I like the OM Zuiko 135/3.5 and it's quite small; and while the Minolta MD-III 135/3.5 doesn't grab me, others like it.

Or if you don't mind dropping back to 100mm, there are some very nice small 100s - I like the OM 100/2.8 and Hexanon 100/2.8.
 
It's sad when you start finding holes in an old favorite lens.

The OM Zuiko 24/2.8 has been a long-time favorite of mine. I've loved how it performs outdoors, with great color/contrast and good sharpness. It has some vignetting on FF, but not enough to be a problem for me; in many cases I think it enhances the look.

But recently I've done a lot of indoor shooting with it, often in dim light, and I've been disappointed in the results. In particular, I'm seeing a lot of uncontrolled flare and light blooming with interior spotlights:

Here's what another favorite of mine, the MD 35-70/3.5 Macro, looked like in comparison:

Sigma fp, MD 35-70/3.5

Sigma fp, MD 35-70/3.5
I feel like the Oly lens provides a bit of a cinematic - or maybe just more dramatic - look with the flare. I like it!

I'll second that take - there are a handful of companies churning out ridiculously expensive filters (all the "mist" filters, diffusion filters, etc) to achieve similar results and videographers are their main target demographic.

That said, without having experience shooting that particular Oly wide, it could be developing a mild case of internal haze. It certainly looks like a great lens still worth using whether that's the case or not.

By the way, Travis - when I click the "original size" links or the "JPEG" links in the gallery view, my browser automatically downloads them instead of just viewing them. If I remove the "_d" suffix of the link, it works like regular uploads. My Downloads folder is filling up fast! ;-)
 
I'm going to jump on the cross-eyed stereo train and post a couple shots from a revisited project of mine - a stereo pair of tiny lenses on a single sensor. The lenses are only just over 22mm apart, so the stereo effect is not that strong, but it still works surprisingly well. It's fun and challenging to shoot with. I finally got around to trying video but I didn't get anything really worthwhile... this time! That's going to require a lot more practice.

First up are a couple of tight crops:

Katydid on a freeway daisy

A fence lizard in his element - even though the right eye has slightly worse image quality, and even though this scene is mostly lacking any depth, I see some real 3D-pop in stereo ;-)

I needed to get closer to this guy but he was too skittish.

Thankfully a neighborhood cat was more willing - here's what it looks like while you're composing shots, which has its complications:

Here's a crop:

And here's a tighter one:

e38696f200ba4719bd7b7adb6695036b.jpg

One may notice that the two samples of this optic render a little differently - the right eye (left side of the images) has all yellow/amber-reflecting coatings for a slightly cooler transmission and shows signs of stressed/tilted elements in tests, while the left eye has a mix of magenta/blue/purple-reflecting coatings that look like they may be doing a better job.
The stereo depth looks fine to me especially in the (eek!) flower shot.
Aww I thought the Katydid would give me a pass!
The short separation of the lenses would be a problem with more distant subjects though.
True! It's very paper-cut-out-diorama-like out there with these dual lens setups. I have to wonder what the ideal separation would be and how it depends on the focal length (or equivalent focal length) of the lenses used - when you're out shooting sequentials, how far apart would you say your shots are? Maybe a test shoot and a poll on the results is on the horizon.
The beautiful thing with a two-lens setup is that you can shoot moving objects. The single lens, sequential method I, and many folk on here use, is pants for anything with movement.

Even flowers, if it is windy :o0
Agreed! I hope to capture some more interesting subjects soon, hopefully some that won't get scared off. I wish I could've been sitting in the Alps under the moonlight with a gentle breeze blowing to record... and take in the scenery (lovely shots, BSWA).

Thank you. Yes, 9 frames stitched. Approcximately 50mm equivalent.

I think my copy was made by Kiron but I'd have to look up the serial number again. I once read that 135mm lenses were easy to get right so there are a lot of good ones out there. Very easy lens to use and always nice results. The aperture is funky on mine and won't close down beyond f/8 or so but you won't hear me complain about having to spend $12 for it.

I can see the argument, but it's emphatically not what I'm looking for here. ^^;;

What I'm trying to showcase in these interior shots is the subjects themselves, whether plane or generator:

Sigma fp, OM Zuiko 24/2.8

Sigma fp, OM Zuiko 24/2.8

And flare like that is distracting from the actual subject, not to mention making it harder to see the subject itself. :(
That said, without having experience shooting that particular Oly wide, it could be developing a mild case of internal haze. It certainly looks like a great lens still worth using whether that's the case or not.
Not sure if it's the lens itself getting worse, or just using it more in situations where it would never work well.

I may end up restricting it to outdoor subjects and times when I want the flare. Still not ideal, since indoor shots like this is one of my main uses for wide angle, but we'll have to see what we can do.
By the way, Travis - when I click the "original size" links or the "JPEG" links in the gallery view, my browser automatically downloads them instead of just viewing them. If I remove the "_d" suffix of the link, it works like regular uploads. My Downloads folder is filling up fast! ;-)
Ah! Well, tried removing it here, so let's see how it works. :)

I was wondering why it moved to downloads; I was copying and pasting the Flickr link as described in one of the guides from that hiccup a couple of years before the closure crisis, when they restricted external photo uploads.

All of these are older shots, but I've recently revisited them and processed a couple more of them (decided that a majority of them were best SOOC however, so I didn't do anything besides resizing):

I've honestly been very impressed by the look of this one. No idea what it is though. It's specs are certainly not that imrpessive and it's very old. But I feel like something is very pleasing about the look.

I posted some pictures with this lens before https://www.dpreview.com/forums/post/68071161. Somehow it made its way to my bag when I got to the same place I posted from at the link above. I am still confused whether it’s a 4 elements Petzval as noted here https://u42.co/Lens-Design/Rollei-Projar-85mm-f2.8-Info/Rollei-Projar-85-f2.8.html since Bosun mentioned before that most likely it’s a very simple triplet. It’s a bit less predictable than triplets I used. I have not yet found the sweet spot for it in terms of application. It does not shine for closeups yet it has a surprising somewhat unexpected bokeh, does well for portraits and is reasonably sharp at long distance.

I ended up trying it with an aperture inserted before an adapter and it only vignettes badly when it is significantly closed. It sharpens up nicely at close distance at about f4-f5.6. Some of the shots with the lilies are closed down but it darkened fast and started raining so I turned up the ISO and hurried up so I can’t remember where I closed it down some. if you see vignette, it’s with an aperture installed.

There is something that I don’t like about the colors. They are a bit brighter yet the sky is somewhat muddy, it was much more like clear blue

I agree with you 100%. The pictures are very gentle, soft but not in a sense of non-sharp, they are sharp like seen by a human eye I think. I really like what the French lenses in general deliver, I think this is the quality, not “scientifically sharp” (??) - perhaps a wrong way to generalize but I don’t have any and examples I saw through the years online may have been from similar manufacturers or period (light on coatings).

Good looking shots! I don't have any hands-on experience with the 85 mm Projar. There are lots of different versions so it's possible that there is some 4 element Petzval type, but Mark lists pretty much all of the (non S-) Projars as 3/3 designs:

https://deltalenses.com/?s=projar

I think a 3 element design is more likely, but who knows. Should be easy to check, even by just looking at the reflections. The book "Photographic Optics" by Arthur Cox does also mention the Projar as a Triplet.

Stephen Cushing (whose article you've linked to) also mentions that the drawing shows a typical Petzval lens, but there's no concrete evidence given that it is indeed the optical layout of the lens shown. I don't think Petzval designs are very common among later slide projection lenses anyway...

All of the Projars (plain vanilla, "P" and "V") I have disassembled were triplets, admittedly they were all of the plastic-bodied type with Kodak carousel threads. It may be that the metal-bodied, faster (f2.4-5) types have a different design, but I have never had one.

Cushing does indeed show a Petzval diagram for his 85mm f2.8 Projar, but how did he obtain the information? All of the Projars and 35mm Heidosmats I have are plastic, like the one in Cushing's piece, the elements of these are held in place by regular spot melting and deformation of the plastic around them. Dismantling this type of construction is a destructive process, the toothpaste will not go back into the tube, and it does not look as though Cushing has had his lens apart.

I have a similar 85mm f2.8 Rollei which I have not tested yet, but if it does prove to be uninspiring, I will open it to see what lies inside. I would be betting heavily on a triplet, the length that the glass is contained in is just too short to be a Petzval.

Triplets seem to be unbiquitous for 35mm slide projectors, but that is a "modern" convention, many early slide projection lenses were 4 element "fast" designs such as Ernostars, or Speedics, presumably used to counteract the dim bulbs used in early projectors.

Note the omission of Petzvals above, even in professional movie projection lenses Petzvals are generally only used above 100mm FL, shorter FLs like the 85mm that is common for 35mm slide projectors are usually all Double Gauss/Planar designs.

Later slide projectors had high output halogen bulbs with fan cooling, and it is in these we see the use of triplets become standard.

The lens diagram in Cushing's piece on the Rollei lens helpfully included a scale. If this is correct, the length between the front and rear elements on his diagram is 80.3mm.

The entire length of the lens tube is only 81mm and the photo shows the front element deeply recessed, so the elements shown in that diagram could not possibly be contained in that lens.

I measured the length of the optical block in my Rollei 85mm f2.8 - 35mm.

The Petzval diagram shown has nothing to do with the lens in the accompanying photo.

A lens with an FL of 85mm that has a 35mm long optical block = triplet.

Nice! It's so much fun shooting stereo images. Everything is just that much more interesting (and lifelike, if you can see it).
The first pair of the cats is hard to look at, because the two frames don't show the same parts (in the right half of the frame you can see a lot more of the cat than in the left one).
I'm looking forward to more stereos from you!

Dear all - sorry for the doubt and not looking at reflections before posting. It is a triplet. It’s just probably the most capricious one from the triplets I’ve used, quite a bit less predictable.
